Alarm Information

Null

Handling Process

This terminal should be separated from other network devices and then it should be reserved only for the maintenance operations related to routers and TMGs. It is not recommended that maintenance terminals access internet because they can get any virus from there.

Root Cause

The terminal is configured on both public and private IP addresses. It uses private IP addresses to manage softx and use public IP address to manage routers and TMGs. The public IP of terminal is in the same subnet as that of softx so there can be any virus or unnecessary packets through this terminal.

Suggestions

So it is suggested that maintenance terminal for softx should be on private IP and for router and TMG (need public IP address because all routers and TMG are on public IPs) the terminal should not be in softx subnet.
